But of course... Egrade says thats and incorrect answer.. Can someone check over my work and help me out.

Also, if u dont mind.

A world's land speed record was set by Colonel John P. Stapp when in March 1954 he rode a rocket-propelled sled that moved along a track at 1020 km/h. He and the sled were brought to a stop in 1.4 s. In g units, what magnitude acceleration did he experience while stopping?

So i realize 1g = 9.8m/s^2

so if i use the formula Vf = Vi + at
and get a. how do i solve for g?

i know you multiply by whatever ur g is and then mulitply that by 9.8. but the answer im getting is not correct. any help would help...

sorry. the only reason i am not using the correct sig. figures is because we use an Egrade program which doesnt require it. so my teacher said it would be better to not use them when we use Egrade, otherwise we must.

Someone needs to slap your teacher along side his head. You need to develop the habit of using the correct number of significant digits. Spewing the entire contents of your calculators display is poor form.
